Python3.7.8 pip安装故障求助：预安装缺失且get-pip.py报Errno9错误

Let's work through this pip issue together—here are actionable steps to get pip up and running smoothly:

First, Check pip's Default Location #

Python 3.4+ does come with pip pre-installed, but it lives in the Scripts subfolder of your Python installation (for you, that's C:\Programs\Python37\Scripts). If this folder isn't added to your system's PATH, you won't be able to call pip directly from any command prompt.

• First, try accessing pip via Python's module syntax (this bypasses PATH issues entirely):

  C:\Programs\Python37\python.exe -m pip --version
  

• If this works, add the Scripts folder to your system PATH permanently to make pip accessible everywhere:
  1. Open System Properties → Advanced → Environment Variables
  2. Under "System Variables", find Path and click Edit
  3. Add a new entry with C:\Programs\Python37\Scripts
  4. Restart your command prompt and test pip --version

Resolve the "Bad File Descriptor" Error from get-pip.py #

This error usually comes from permission issues with temporary files or compatibility gaps between the latest get-pip.py and older Python versions like 3.7. Try these alternatives:

1. Use Python's Built-in ensurepip Module #

This is the most reliable way to repair or install pip for your specific Python version—no need for external scripts:

# First, run Command Prompt as Administrator
cd C:\Programs\Python37
python.exe -m ensurepip --upgrade

2. Run get-pip.py with Administrator Privileges #

The error might be because your user account doesn't have permission to write to the temporary folder (C:\Users\Susanta\AppData\Local\Temp). Right-click Command Prompt → "Run as administrator", then re-run:

cd C:\Programs\Python37
python.exe get-pip.py

3. Check for Security Tool Interference #

Some antivirus or firewall tools block write access to temporary folders. Temporarily disable these tools while installing pip, then re-enable them once the process finishes.
